How to make an AI avatar videoin three steps

  1. 1

    Pick the face

    Upload a photo of the presenter, or pick a Persona, a face saved to reuse. Make one from your photos, a description or the Builder, or pick a Featured Persona: a ready-made presenter you can use as it is.

  2. 2

    Give it a voice

    • Type the script and pick a voice. Eleven v4 reads the widest list of languages.
    • Record a sample of your own voice once and use it in every video.
    • Upload a recording you already have.
  3. 3

    Pick the model and the shape

    Choose 9:16 for phones or 16:9 for courses and players, check the length fits the model, and generate.

One presenter, a whole seriesMake Sami once. Use him everywhere.

Sami is a Persona: a face and a voice saved together. Put him in any scene with the image generator, then make each scene talk. His face and voice stay the same, in English or in Spanish.

    Weekly update, 16:9

    Hi, it's Sami. Three new plants came in this week, and all three are very hard to kill.

    Care tip, 9:16

    Water it when the top inch of soil feels dry. Not before. Most houseplants die from too much love.

    This pot hides its own saucer, so the water stays in and your windowsill stays dry.

    Welcome, in Spanish, 16:9

    Hola, soy Sami. Bienvenidos a la tienda. Si buscan una planta fácil, pregúntenme.

How long can it talk?Pick the model by the length of your script

Each bar runs from the shortest to the longest audio a model takes. A calm presenter reads about 150 words a minute.

About 75 words. 6 models fit

Infinitalk

Long talking videos. No set length cap. 480p or 720p.

HeyGen Avatar IV

Talking-head presenters from one photo. Up to 3 minutes. 9:16 or 16:9.

Mirage Avatar X

Realistic talking heads. 3 seconds to 3 minutes. Photo must be 9:16 or 16:9.

OmniHuman 1.5

Expressive, full-body presenters. Up to 60 seconds at 720p, 30 at 1080p.

Kling Avatar 2.0

Talking avatars up to 1080p. 2 to 60 seconds.

VEED Fabric 1.0

Short presenters from audio or a typed line. Up to 30 seconds. 480p or 720p.

Grok ImagineToo long

Reads a typed line. 6 to 15 seconds. 9:16 or 16:9.

Wan 2.5Too long

Talking clips with a scene prompt. 5 or 10 second videos, up to 1080p.

Veo 3.1Too long

Reads a typed line, up to 4K. 8 seconds. 9:16 or 16:9.

Veo 3.1 and Grok Imagine read a typed line, so their length is the video length. Veo 3.1 Fast has the same 8-second limit. Infinitalk takes longer audio. For the others, split a script longer than 3 minutes and make one video per part.

The photo decides the videoGive the model a face it can read

The avatar model animates the photo you give it, background and all. Frame it the way the video should look.

A woman faces the camera in even light, her mouth in view

This photo works

  • Faces the lens, both eyes in view
  • Mouth visible and free
  • Even light on the face
  • Framed as the video will be: 16:9 or 9:16
  • The same woman turned away toward the window

    Turned away

    The model sees half a face and has to guess the rest when she talks.

  • The same woman with a mug covering her mouth

    Mouth covered

    A mug, a hand or a microphone in front of the lips leaves nothing to move.

  • The same woman with a bright window behind her and her face in shadow

    Backlit

    A bright window behind the face drops it into shadow, and the detail goes with it.

  • Mirage Avatar X takes only 9:16 or 16:9 photos, at least 512 px on the short side. The other models set no photo shape.
